Cadmium Sulfide
CADMIUM
Hazards
- Cadmium
Miscellaneous
- Family: Flux Source
- Region: None
- Mined At: Unspecified
- Raw Mineral: No
- Generic: No
Notes
CdS. Mol Wt. 144.47; Specific gravity: 3.8-4.8, melting point: 900C.
It is practically insoluble in water but soluble in ammonium hydroxide and acids. The material occurs as the mineral greenockite, which is recovered as a byproduct of the refining of zinc ores. It is oxidized to the sulfate and then reprecipitated as chemically pure cadmium sulfide by hydrogen sulfide.
Cadmium sulfide is a important source of both cadmium and sulfur. They complement each other in producing yellow and red colors in enamels and glasses. Often, selenium is used in the compounds.
